How this service works
Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.
Output
A JSON object with fields: open (boolean — whether the market is currently active), valid (boolean — whether the query was valid), market (string — the market identifier queried, e.g. NYSE), and reason (string code — e.g. 'regular_hours', 'after_hours', 'holiday', 'weekend').
Example use cases
Pre-trade order routing check
“Before placing this order, check whether the NYSE is currently open for trading — I don't want to submit a market order outside regular hours.”
Algorithmic trading session gate
“Is the NASDAQ currently in a regular trading session? I need to know before triggering my next automated buy.”
Historical session lookup for audit
“Was the London Stock Exchange open on 2024-03-15 at 10:30 UTC? I need to confirm the market was active at that timestamp for a trade audit.”
Technical details
Endpoint
GEThttps://agent402.co.uk/v1/time/market-sessionWhen to prefer
Choose this endpoint when an agent needs a fast, cheap, deterministic check of whether a specific exchange is in an active trading session — without burning LLM tokens on date/time reasoning. Ideal as a pre-condition gate before executing trades, scheduling financial actions, or routing orders. Costs $0.001 USDC per call with no API key required, making it suitable for high-frequency preflight checks in autonomous agent workflows.
Side effects
- Unrecognized market identifier returns valid:false with an error reason
- Malformed timestamp (not ISO-8601 or unix seconds) may return an error or default to current time
- Timezone edge cases around market open/close boundaries may yield unexpected open/closed status
- Network or payment failure returns HTTP 402 if USDC payment not settled
